lead

lead (Pb)

[led]

Etymology: ME, leed

a common soft blue-gray metallic element. Its atomic number is 82 and its atomic mass is 207.19. In its metallic form, lead is used as a protective shielding against x-rays. Lead is poisonous, a characteristic that has led to a reduction in the use of lead compounds as pigments for paints and inks. Normal concentrations in whole blood are 0 to 5 μg/dL. The normal amount in urine after 24-hour collection is less than 100 μg.

lead

1. An electrical conductor carrying current or intermittent signals between an organ or tissue and an electrical or electronic device.

2. The tracing obtained from a particular combination of electrode positions.

lead

(Pb) (led)

A metallic element, atomic no. 82, atomic wt. 207.2; occurs in nature as an oxide or one of the salts, but chiefly as the sulfide, or galena; 210Pb (half-life equal to 22.6 years) has been used in the treatment of certain eye conditions. Synonym(s): plumbum.

[L. plumbum]

lead

1. A malleable heavy metal with poisonous salts.

2. An electrical connection or electrode by which currents are conveyed to or from the body.

Lead

lead,

n a toxic metal that can be found in lead-based paints, leaded solder joints, and some fuel substances. Exposure has been linked to poor functioning of central nervous system as well as learning and behavioral difficulties.

lead

(lēd)

An electrocardiographic cable with connections within the electronics of the machine designated for an electrode placed at a particular point on the body surface.

lead

(lĕd)

A metallic element, atomic no. 82, atomic wt. 207.2.

[L. plumbum]

lead (Pb),

n a common soft, blue-gray, metallic element. Its atomic number is 82, and its atomic weight is 207. In its metallic form, it is used as a protective shielding against radiographs. (In dentistry, lead acts as a protective shield against the radiographic beam and is found in the lead apron and walls of the surrounding operatory.) It is poisonous, a characteristic that has led to a reduction in the use of lead compound as pigments for paints and inks.

Patient discussion about lead

Q. Does lead harm fetuses?

A. Lead is highly teratogenic. it affects the fetus Central Nerve System - the CNS. and unfortunately the fetus is very sensitive and absorbs the lead from the mother body. therefor damage to the fetus is higher then to the mother, that means she can be unharmed and the fetus can be affected. because the CNS is built throwout the pregnancy (after the 18th day) it can do damage if exposed at that time.i hope i'm not the bearer of bad news...

Q. What are the chances that chronic depression leads to schizophrenia? Someone close to me has been battling depression for 17 years now. She is doing a good job, has held on to a demanding job for 4 years now. Though her performance at work are highly erratic. Periods of poor apathetic performance interspersed with periods of high performance.
She shows symptoms of chronic depression, withdraws from social life, has low energy, can spend days in bed, is messy etc. She's on medication too.
I fear that the next phase will be schizophrenia

A. Sometimes if you forget to take your medication, you can have bad days. It could be from not getting enough sleep, something stressful going on in personal life, job stress, some big change. There's a long list....I am not an expert on depression, but I don't think it leads to schizophrenia. Not exercising can certainly lead to other health problems. Everything can go into the death spiral if you just ignore everything and quit taking care of yourself.

You mentioned this was about a friend. So maybe, you have to do what a real friend needs to do. Some people will not help themselves and will let others do everything for them. If that's the problem, saying NO may be just the thing to get them to do things for themselves, like they should be doing. So if you are babying your friend, then maybe that's not really in their best interest. I don't know what's really gong on in your situation. So my suggestions could be way off. Its impossible for me to understand it with just the few w

Q. What are the leading causes of depression and anxiety in women today? Females suffer from anxiety and depression at twice the rate of men. In fact, mental disorders such as anxiety and depression are the leading cause of disability for women.
What are the leading causes of anxiety and depression in women? Please provide as credible sources as possible. Thank you.

A. I know from experience, hormones. When I was on birth control it made me nuts - anxiety and panic attacks. Mood swings and crying over nothing. Many of my friends have also experienced this on BC - and some who were never on BC started taking it and it balanced them out. So I really believe that hormones play a huge part. Also thyroid problems too.
